Title: Hydroxyl-containing compositions and their polymerisation
IPC: C08G75/045
Filed: 1979-01-05
Abstract: Polymerisable compositions comprise   a) a compound containing in the same molecule both at least one phenolic hydroxyl group and at least two groups chosen from allyl, methallyl, and 1-propenyl groups, e.g., 2,2-bis(3-allyl-4-hydroxy- phenyl)propane or bis(3-(1-propenyl)- 4-hydroxyphenyl)methane. b) a compound containing at least two mercaptan groups per molecule, e.g., pentaerythritol tetrathioglycollate, and c) a heat-activated crosslinking agent for phenol-aldehyde novolac resins.   The compositions are caused to polymerise by the action of irradiation or free-radical catalysts. The polymers so obtained, containing more than one phenolic hydroxyl group, can be subsequently crosslinked in situ by heating. The compositions are useful in various two-stage operations, such as the production of multilayer printed circuits. Polymerisable compositions may also comprise   d) a compound as a) but containing at least two phenolic hydroxyl groups, e) a compound containing more than two mercaptan groups per molecule.     On irradiation or on heating with a free radical catalyst, these compositions crosslink; they are useful in forming coatings on polar substrates.

Title: Textile drawing mechanisms
IPC: D01H5/50
Filed: 1955-12-07
Abstract: 792,779. Textile drafting mechanism. SKF KUGELLAGERFABRIKEN GES. Dec. 7, 1955 [Dec. 8, 1954; Jan. 20, 1955], No. 35150/55. Class 120(2) Textile drafting mechanism which comprises a top apron supporting cradle and a top roller carrier arm 1 which can be raised from the plane of the drafting field and carries saddle-shaped seatings 8, 9, for supporting the top rollers 10, 11 is characterized in that means 15, 17 are provided for ensuring a sliding guided engagement of the cradle and the seatings 8, 9 whereby these parts are maintained in correct assembled relation. Preferably, circular guideways 17 are provided on the cradle to engage circular guideways 15 on the seatings 8, 9 and the cradle has sides 16 to restrain the cradle against movement longitudinally of the roller axis. The cradle is preferably retained on the arm 7 during insertion and removal of the top roller 10 by a screw 22 screwed into the arm 7 through a slot 21 in an apron-guiding plate 20, and a spring 25 is positioned between the plate 20 and the arm 7 to urge the plate 20 towards the bottom apron 24, the distance between the top apron 26 and the bottom apron 24 being adjustable by means of an adjustable or exchangeable pin 27. Preferably, the arm 7 is pivotally mounted at 6 on a bracket 5 of the lever 2 pivoted in the carrier arm 1, the arm 7 being loaded by springs 12, and its downward vertical movement being limited by stops 13 and 4 on the arm 1. Annular segments are fitted on the cradle and are received in corresponding recesses in the seating 8. The centre of the inner circumference of the segment on the seating 8 may be off-set from the centre of the outer circumference, in which case the spring 25 is unnecessary. In a modification, there is a semi-circular segment on either side of the seating 8 facing downwardly and received in semicircular recesses in the cradle. When in normal operation, the openings do not conincide, so that the top roller shaft 10 is retained in position, but for removal of the top roller, the openings may be brought into coincidence. In a further modification, the inner circumference of the annular segment is eccentric to the outer circumference of the segment, and the spring 25 in the embodiment shown in Fig. 1 is rendered unnecessary.

Title: Improvements in or Relating to Visual Display Apparatus
IPC: G02B27/00
Filed: 1979-12-19
Abstract: The invention provides head- coupled area-of-interest visual display apparatus particularly for ground- based craft-flight simulators. The apparatus provides binocular, pseudo- collimated vision of a display for both pilot and co-pilot projected onto the inside of a part-spherical shell, which carries a concave retro-reflective screen and surrounds the two pilots. The displayed scene covers an area of interest centred upon each pilot's line of view. A separate image generator is used for each pilot and may be of the computer generated image, laser- scanned model or closed-circuit television type. For the pseudo- collimated viewing, the same image is projected for left and right eyes for each pilot from points on a respective pilot helmet, above the pilot's eye position. Line scan apparatus is mounted in the pilots' cockpit; line image transmission is by fibre optic light guide ribbons; and frame scan apparatus is mounted on the two pilots' helmets. Sensing means detect head/helmet movements of each pilot to permit voluntary individual scanning of a wide angle of simulated view from the craft. <IMAGE>
